i have a dual voice coil 4 ohm subwoofer. I'm wiring it up so it gets a 2 ohm load. How do I go about wiring it up to a 2 ohm load?

 

at this site it shows that in a dual voice coil sub run in parrell must take a postive off one side of the sub and a negative off of the other side of the sub.

When I wired mine up i just took the postive and negative off of the one side of the sub. DOes it really matter?

 

you are correct sir

 

No, you have to hook it up the way the picture says. If you only hook up one voice coil, you will have a 4 ohm load. You need to connect the positives to each other and the negatives to each other then hook that to the amp.

 

I have also heard that only hooking up one voice coil can damage the sub. True???

 

i actually hooked one positive off of the sub to other positive on the otherside of the sub. Then I did the same for the negatives. Then I just ran a positive and negative off of one side of the sub to the amp.. This is the proper way to obtain a 2 ohm load correct?

 

It is possible to damage the sub if you only have one voice coil being powered, yes.

 

so my sub is hooked up the right way correct

 

that is correct. you need all + one one line and all - on the other if you doe +-+- you will get a 8ohm load, ++, -- will give you a 2ohm load.

As far as not running both coils at once it is safest to run both at once.
